Cargo cults have been recorded since the 19th century, but have been continuously growing since World War II. The cult participants generally do not fully understand the significance of manufacturing or commerce. They have limited purchasing authority. Their understanding of western society, religion, and economics may be rudimentary. These cults are a response to the resulting confusion and insecurity. They rationalize their situation by the reference to religious and magical symbols they associate with Christianity and modern western society. Across cultural differences and large geographic areas, there have been instances of the movements independently organizing.
The most famous examples of Cargo Cult behavior are the airstrips, airports, and radios made out of coconuts and straw. The cult members built them in the belief that the structures would attract transport planes full of cargo. Believers stage "drills" and "marches" with twigs for rifles and military-style insignia and "USA" painted on their bodies to make them look like soldiers.
Today, most historians and anthropologists argue that the term 'Cargo Cult' is a misnomer that describes a variety of phenomena. However, the idea has captured the imagination of many people in developed nations, and the term continues to be used today. For this reason, and possibly many others, the cults have been labelled millennialist, in the sense of a utopian future brought about by a messiah.A similar cult, the dance of the spirits, arose from contact between Native Americans and the Anglo-American civilization in late 19th century. The Paiute prophet Wovoka preached that by dancing in a certain fashion, the ancestors would come back on railways and a new earth would cover the white people.
A religion described as a "cargo cult" developed during the Vietnam War among some of the Hmong people of Southeast Asia. The core of their beliefs was that the second coming of Jesus Christ was imminent, only this time he would arrive wearing camouflage fatigues driving a military jeep to come and take them away to the promised land. The origins are unknown, but one can surmise that it was assembled out of the images of new power apparent to them in that time period, in the form of the American military and of western Christian missionaries.
A more recent example of a mythological worldview misinterpreting scientific practices occurred in Africa, where an aid organization, focusing on slowing and stabilizing population growth, distributed abaci with red and white beads corresponding to a woman's menstrual cycle. Women were instructed to move one bead a day, only having intercourse on days represented by a white bead. However, the experiment failed, and the population grew in the households using the abacus. The women believed the abaci were magical, and that they would be protected from pregnancy by moving a white bead into the place of the red bead before intercourse.
